3x+y=6
4x+2y=8
substitute
y = -3x + 6
4x+ 2(-3x + 6) = 8
4x -6x +12 = 8
-2x + 12 = 8
-2x = -4
x = 2
y = -3x + 6
y = -3(2) + 6
y = 0
(2,0)
3x+y=6
4x+2y=8
how do you solve this?

3x+y=6
4x+2y=8
y = 6 - 3x
4x + 2(6 - 3x) = 8
4x + 12 -6x = -4
-2x = -8
x = 2
Substitute 2 for x in the first equation to find the value of y.
4x+2y=8
y = 6 - 3x
4x + 2(6 - 3x) = 8
4x + 12 -6x = -4
-2x = -8
x = 2
Substitute 2 for x in the first equation to find the value of y.
